My doctor found minimally tender prostate and benign feel prostate.. Is this prostatitis? I had no pain when he pushed the prostate... my urine test showed e coli infection...  he has advised three different antibiotics for 3 months for bacterial prostatitis.. ciprofloxacin for 1st month , Bacstol for 2nd month and , And Niftas for 3rd month. Can taking a certain antibiotic for 30 days cause resistance to antibiotic...?? And plz tell if these medicines are appropriate?? I have these symptoms for one month now...
